- Server: Sap Btp Destination (`facusada/mcp-btp`) — https://policylayer.com/tools/facusada-mcp-btp.md
- Homepage: https://github.com/facusada/mcp-btp
- Risk category: Other (Low risk)
- Registry record: grade D, identity unverified

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "async_tool",
    "arguments": {}
  }
}
```

## Why async_tool is rated Low

The description is empty and the name 'async_tool' is uninformative on its own. Without any evidence of what this tool does, it cannot be reliably classified. Given the server context (SAP BTP Destination Service), it may relate to asynchronous operations, but this is speculative. Confidence is very low and defaulting to Other.

From the tool's own definition: "Tool name is 'async_tool' with an empty description, providing no information about what the tool does."

## Use case

AI agents call async_tool as a supporting operation in Sap Btp Destination workflows.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sap Btp Destination:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "async_tool": {
      "limits": [
        {
          "counter": "async_tool_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
